Progressive hip joint subluxation in Saul-Wilson syndrome.

Saul-Wilson syndrome (SWS) is a rare congenital skeletal syndrome characterized by postnatal onset of short stature, relative microcephaly, frontal bossing, prominent eyes with shallow orbits, midface hypoplasia, cataract, and generalized skeletal changes, including spondylar dysplasia, overtubulation of the long bones with metaphyseal flaring and megaepiphyses, coxa valga, elbow deformity, and brachydactyly. We describe a boy with the overall clinical and radiological features fitting the characteristics of SWS, although cataract, elbow deformity, and overt brachydactyly were not seen. He presented with painful hip joint due to hip subluxation in late childhood, which exacerbated with age and ultimately, required surgical intervention. Awareness of this orthopedic complication in SWS is essential in the management of patients with SWS.
